This is basically how I see how Emile would fit into the proper MCU movie plots.
NY Attack (2012)
Emile is 17
He isn't technically an Avenger yet (Steve doesn't want to put kids at risk)
He kinda watches things from the tower but wants to help with catching Loki.
Pushed out of the way by "SHIELD" and called a brat. Unamused.
Winter Soldier (2014)
Emile is 19
Emile hates and wants revenge on Bucky, not fully trusting him in the future when he believes Bucky killed Nick Fury.
Ultron (2015)
Emile is 20
Emile is skeptical about the idea of Ultron, but tries to trust Tony's best efforts. Suprise suprise, we all know what happens next.
When he tries to help evacuate people, Emile is almost crushed by a huge chunk of falling debris. Scarlett Witch saves him, which distracts her and she doesn't know what happens to her brother.
He is very, very skeptical of Vision.
He tries to follow Hulk, attempting to calm the male but, instead, they both are trapped on a ship in PANIC.
Sakkar (2017)
Emile is 22
Life isn't the worst of Sakkar, but it isn't Earth. Parties are every night and, the same thing was starting to get a big...boring.
He sort of is one of those people that sit at the Grandmaster's side to compliment him, meeting a male who made him have reminders from the past...but who was he?
Then, Thor arrived.
While Thor was there, Emile manages to sneak off into a ship to return home, safe but unable to place where he saw the dark haired male from.
Infinity War/ Thanos Time (2018)
Emile is 23
The male is sent off to Wakana with the belief that he will be able to stay safe and out of the way...which obviously backfires. He is in the lab, trying to contact Tony and keep Vision calm, which felt pointless. How do you keep someone calm when they believe they're going to die?
When someone had broken in after Wanda left, he had ducked back and struggled to contact the missing team, sending out warning that Vision was in danger. He nursed those injured.
He doesn't survive the snap/blip.
End Game (2023)
Emile returns, still 23.
He stays back further in the fight, transferring pain from our heroes onto the villains, driving them with so much madness they end their lives.
Also, he is awesome with a gun. His glasses give him nearly perfect aim with throwing knives but, those are short supply.
Spiderman (2023?)
Emile had met Mr. Beck and, he wasn't sure exactly if he believed the story he told. Too many people in the past had lied to him.
He is working to try to track down this "Peter Parker" aka, Spiderman to assist with helping Mr. Beck. Only, this is a kid who Emile believes should get to finish growing up first.
He kinda was along for the ride, not having too much say as he was trying to silently put everything together.
He had stepped aside, looking over things before piecing together the truth about Beck.
Only, Mysterio trapped him in an illusion to keep him from spilling the beans when he realizes this.
Spiderman unintentionally saved him, being caught in his own illusions and then getting hit by a train.
Instead of going to his father with the facts, he tries to go after Peter, but isn't able to catch up before he is picked up by a private plane.
Emile goes back to seek Fury but is again, trapped by Mysterio and his illusions, driving him into a small state of madness.
Mysterio makes him relieve watching Fury die but in a more realistic way with a not-so-happy ending.
At the end, he was forced to watch Mysterio record Peter's identity, unable to do anything other then hope the kid could stop Mysterio.
Obviously, Peter stopped Mysterio, but his identity was leaked, leaving Emile to feel guilt, though he couldn't do anything to help.
